Using Arduino with Piezo Sensors:
Advantages of using Piezoelectric sensors:
- Extremely high rigidity
- Hight natural frequency
- Extremely wide measuring range
- Very high stability
- High reproducibility
- Wide operating temperature range
- Insensitivity to electric and magnetic fields

The videos below show the power of this type of sensor and how it can be used with max/msp, including triggering samples and 'playing' everyday items. Also shown as a contact microphone and how it can be used to record different surfaces and items.
